The role of large-scale magnetic fields in galaxy NGC 891. Can magnetic fields help to reduce the local mass-to-light ratio in the galactic outskirts?
Joanna Jałocha, Łukasz Bratek, Jan Pȩkala +1
We address the problem of the influence of large-scale magnetic fields on galactic rotation for the example of the spiral galaxy NGC 891. Based on its rotation curve and the surfac…
A lower bound on the Milky Way mass from general phase-space distribution function models
Łukasz Bratek, Szymon Sikora, Joanna Jałocha +1
We model the phase-space of the kinematic tracers using general, smooth distribution functions to derive a conservative lower bound on the total mass within 150-200 kpc. By approxi…
Gravitational microlensing as a test of a finite-width disk model of the Galaxy
Szymon Sikora, Łukasz Bratek, Joanna Jałocha +1
The aim of this work is to show, in the framework of a simple finite-width disk model, that the amount of mass seen through gravitational microlensing measurements in the region $0…
